According to Spanish newspaper El Faro de Vigo, the lawyer overseeing the case has formally requested a two year ban from the Spanish Cycling Federation’s disciplinary committee.

At first glance, the hard line being taken on Mosquera’s case contrasts sharply with that of Alexandr Kolobnev by the Russian Federation, also positive for a masking agent – in Kolobnev’s case during this summer’s Tour de France. Kolobnev is strongly rumoured to have been let off with a warning, although this has yet to be formally confirmed.

However, although Mosquera could technically receive the maximum sentence possible, a two-year ban is only a recommendation, not a definitive sentence.

In the case of Alberto Contador’s positive for clenbuterol, for example, a year’s ban was proposed, but the Federation’s disciplinary committee ignored it and Contador has been racing all season. Mosquera, on the other hand, has not taken part in any races even though technically there is nothing stopping him.

The other most recent case of a positive for hydroexthyl starch – that of former Tour de France Best Young Rider Oscar Sevilla this September – also suggests that a two-year ban is extremely unlikely. Sevilla, like Mosquera a former Vuelta runner-up and currently racing for a small Colombian team, was banned for six months.

One of the longest-running currently unresolved doping cases, Mosquera tested positive alongside his former Xacobeo-Galicia team-mate David García Dapeña for hydroxethyl starch in last year’s Vuelta.

García Dapeña also tested positive for EPO, which he subsequently recognised he had used, although he insisted his was an isolated case which had nothing to do with Mosquera. García Dapeña has since retired.

According to WADA rules, hydroxethyl starch is a ‘specified substance’, given that it can be used as a masking agent to hide use of EPO and other substances, but it is only banned if injected intravenously.

Meanwhile it has been revealed that the 2011 Vuelta a Espana has had no positive doping cases.
